UPDATE: I've added an arrow to those reported as having an arrow in the triangle... Just for kicks... It's the -> that follows the serial...

Sorry bud. Just noticed you wanted Gs...
Got to dig through the room again and recheck the list for you tomorrow.
No G on the 1972.
I'm getting drunk. The commie who stamped it must have been drunk also. So I can't tell till I sober up and recheck the 85 for you.

AHH NO. CALL ME PARINIOD BUT TO MANY ANTI GUN GUYS USING INFO LIKE THAT FOR THE WRONG RESONS. IT WOULD BE REAL EASY FOR SOME NUT BALL TO SAY HIS GUN NUMBER 6969XX WAS STOLEN AND THEN REPORT HE SAW IT HERE ECT JUST TO HAVE ME HASSELD. OR POSSABLY THE DAY WHEN THE LAW DECIDES TO CONSFICATE THAT THEY SHOW UP LOOKING FOR GUN NUMBER FU-69XX BECUSER THEY KNOW I GOT IT. ITS LIKELY NOT A BIG ISSUE JUST A LITTLE TO PERSONAL FOR ME. YOU HAVE THE INFO WITHIN 99 GUNS. IF YOU GET WERE YOU CAN START SHOWING A BREAK DOWN OF DIFFERANT TYPES OF MARKINGS IN RUNS SMALLER THAN 100 THEN I MIGHT RECONSIDER. THANK YOU FOR UNDER STANDING.

It can be shown that given a bunch of serial numbers from a consecutive set of serial numbers you can statistically estimate how large the production run was. In fact, the Allies were able to do that with German tank production during WW II. (Google "German Tank Problem") So, the East Bloc, sneaky types that they were, may have assigned numbers non-consecutively as a counter-intelligence measure. Our nuclear weapons and equipment had serials assigned from randomly generated lists specically for that reason.
